I love Dembele at my club, and hope he can sort himself and stay for at least an another window and prove himself a £30 million player.
Need to bear in mind he is only just 22 and has a lot to learn. BR will know that and attempt to cover and accept faults within reason.
I saw a recent comment quoted to BR, that effectively ended with BR saying," Dembele stays because the deal is not right for both sides and has to be, Dembele may not understand that now but he will in time".
I did suspect however that in the last window Dembele was not the one promoting himself out the door! It could have been an agent or simple misunderstanding, but it could also have been PL seeing £millions.
